hilo explicando lo de los neumáticos (otra vez, pero con más detalles)
estos detalles:

la explicación más plausible:
Somebody reached deeply into a storage depot somewhere in the Russian Federation to get those Cold War era tires because there was nothing else.
You don't put something that potentially dangerous on a major weapons system unless you are desperate. Even if you are Russian.
This, BTW, is why technical intelligence units collect all the manufacturing information on captured equipment to build files on where/by whom/when enemy kit is made.
It gives you trends on the enemy economy you can find nowhere else.
Like Russia is short of truck tires.
